CLIP FOR WHIFFLETREES.

SPECIFICATION forming part of Letters Patent No. 383,900, dated June `5, 1888.

Application filed October Q5, 1887. Serial No. 253,316. (No model.)

.To all whom t may concern:

Be it known that we, WILLIAM M. MYERS and AUGUsTUs SMITH, citizens of the United States, residing at Cosby, in the county of Andrew and State of Missouri, have invented certain new and useful Improvements in Clips for Eveners, of which the following is so full, clear, and exact a description as will enable others skilled in the art to which our invention appertains to makeand use the same, reference being had to the accompanying drawings, in whichtFigure l is a transverse section of our improved clip for eveners, showing it as securing the single and double trees together. Fig. 2 is a longitudinal section of the same; and Figs. 3 and 4 are atop and a bottom plan, respectively, showing the manner of attachment to the trees.

Like letters of reference designate like parts in the several views.

The object of our invention is to construct a clip for eveners which will be extremely simple in its construction, inexpensive in its cost of manufacture, and in which the durability of the singletree will be greatly increased.

Another object of our invention is to construct a device ofthe character set forth, which will permit the singletree to have an extended range of movement wit-hout damaging itor the e 1p. Y

The object, further, of our invention is to construct a clip for eveners which will allow the singletree to have free and easy movement, and which will positively prevent its rattling.

Still another object of our invention is to construct a device of the above character, in which the entire friction will be below the singletree, so that the device can be tightened to any extent desired without interfering with the movement of the singletree.

Still another object of our invention is to construct a device of the character set forth, which will be capable ot being tightened to compensate for wear in the singletree.

The objects, generally, ef ou rinvention are to construct a cli p for cveners which will obviate the disadvantages heretofore experienced in devices of this character, and to provide one which, from its simplicity of construction, cheapness of manufacture, and durability, will readily recommend itself to the great masses of people requiring such a device.

To these ends our invention consists in certain peculiarities inthe construction, arrangement, and combination of parts, substantially as hereinafter described, and particularly pointed out in the claims at the end of the specification.

Referring to the drawings, A represents a doubletree, and A the sin gletree. The doubletree and the singletree are secured together by means of the clevis B, the lower extremities, c a, of which are screw-threaded and iit into perforations b b, formed in a plate, C, secured to the bottom of the doubletree, andthe clevis B is held securely against displacement by means of nuts D D. It will be observed that the portion of the doubletree with which the clevis comes into contact is recessed, in order to permit the same to be partially embedded in the said doubletree to prevent loosening and displaeementof the parts. A bolt, H, extends entirely through the single and double trees, and is formedwith a head, h, at its upper extremity, and is screw-threaded at its lower extremity for thereeeption of a-nut, H', by means of which the device can be adjusted to eompensate for wear in the singletree, or for any other purpose. The plate C is preferably formed with lugsc' at either extremity, against which the whiftietree abut-s, and which obviously keeps the whifetree from lateral displacement and serves to strengthen the said plate at the point `where strength is essential, as will be readily comprehended.

The portion B of the clevis B, which is situated above the doubletree and opposite the singletree, is curved outwardly or distended, as shown. This is a feature of prime impor tance in our invention, inasmuch as it permits r the singletree to have an extended range of movement without coming into contact with the clevis or the si ngletree to injure it or the singletree, which was a frequent occurrence with the old forni of straight clevis, as when the singletree became worn or loose it would oscillatc a greater distance than before, and by coming forcibly into contact with the said clevis was liable to bend and break it and the singletree. The upper extremity of the clevis Bis formed with an enlargement or head, c,

having a slot, d, for the reception of the bolt H, and also with adownwardlyprojecting lng, F, likewise formed with a slot registering With the slot d, and preferably made smaller in circumference than the head c, for the purpose hereinafter' described.

A plate, G, is secured to the top of the sin- .gletree, and is preferably enlarged at its central portion, which is formed with a slot, G', for the reception of thelug F, which construction, it will be observed, will keep the parts in position, even though the bolt H were'to become broken, and thus furnishes a double security in case of breakage.

The under side of the singletrce is provided with a plate, I, which may be secured to it in any suitable and well-known manner, and is formed with a circular lng or projection, J, at or ncar its circumference, and also with a lug or projection, K, at its center, having a slot, K', for the reception of the bolt H; and the upper side of the doubletree is provided with a bearingplate, L, having a lug or projection, M, corresponding in form to the lug K, but made of sufficient size to encircle the said lug K, and the said plate L is also formed with a lug or projection, N, at its center, which receives the lug K, and is likewise formed With a slot, N', for the reception ofthe bolt H.

From the foregoing it will be observed that the bearing for the singletrec is formed by the plates G and L, which coincide With each other and which are held from accidental displacement by means of the bolt H, which passes through the said plates and through the Whiffietree and si ngletree to and through the upper extremity of the clevis B, and is held from displacement byl the nut at its lowermost extremity, which obviously permits the device to be adjusted to compensate for the usual wear in the singletree, and thereby prevents rattling.

Another important fact to be observed is that when the clevis is tightened the junction of its straight portion and curved portion will receive the pressure and transmit it to the bearingplate L, which,obviously, Will effectually tighten the clevis on ythe doubletree without causing any friction above the said bearingplate, and the movement of the singletree Will not be interfered with, no matter how tight the clevis might be secured.

We do not wish to be understood as limiting ourselves to the precise construction and arrangement of parts herein set forth, as many of the details might be varied at will Without departing from the general spirit of our invention or in any manner interfering with its usefulness.

Having now described the construction, objects, and advantages of our invention, and having described a preferred means of carrying the same into effect, whatwe believe to be new and desire to secure by Letters Patent, and What We therefore claim, is

1. In a clip for eveners, the combination, with the whiffletree and singletree, of a clevis having its upper portion curved outwardly and formed with a down Wardly-projecting lug, and aplate on the singletree, substantially as shown and described. i

2. In an evener-clip, the combination, with the doubletree, a bearing-plate secured thereto having outer and inner circular lugs or pro jections, of a singletree also provided with a plate having corresponding lugs or projections adapted to encircle those of a doubletree, a clevis having its ends passing through openings of the doubletreeplate, and a bolt passing through the opening of the clevis and through openings of the plates and single and double trees, as shown and described.

3. In an evenerlclip, the combination, with the Whifletree having grooves in itssides, for the purpose set forth, and the singletree, of a clevis having screwthreaded extremities and consisting of a straight portion and a distended portion, the straight portion being partially embedded in the Whifiletree, nuts on the said clevis, a plate on the bottom of the whiffletree having iianges at either extremity and formed with perforations for the reception of the eX- trernities of the clevis, a bolt for securing the parts together, and a nut on thelextremity of VILLIAM M. MYERS. AUGUSTUS SMITH.
